Abstract

The invention belongs to the technical field of air conditioners, and aims to solve the problem that the self-cleaning control mode of the existing air conditioner is generally slow in frosting speed,so that the whole self-cleaning time is long, and the normal experience of users is affected. Therefore, the invention provides a self-cleaning control method for an air conditioner. The air conditioner comprises a refrigerant circulation system which is composed of an indoor heat exchanger, an electronic expansion valve, an outdoor heat exchanger, a compressor and a four-way valve, and a solution circulation system which is composed of an indoor solution film, an outdoor solution film, a liquid pump and a liquid storage tank. The self-cleaning control method comprises the following steps ofreducing the opening degree of the electronic expansion valve and increasing the rotating speed of the liquid pump under a heating working condition to frost the outdoor heat exchanger; after the outdoor heat exchanger is frosted, closing the electronic expansion valve first, and then closing the electromagnetic valve on the low-pressure side of the compressor after a preset time passes; heating the outdoor heat exchanger to defrost and clean the outdoor heat exchanger. The self-cleaning control method can improve the self-cleaning efficiency of the outdoor heat exchanger and improve the userexperience.

Description

technical field

[0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for an air conditioner. Background technique

[0002] The air conditioner is a device that can cool / heat the room. As time goes by, the dust accumulation on the indoor and outdoor units of the air conditioner will gradually increase. , which is exposed to the outdoors for a long time, making the dust and bacteria from the outside easily adhere to the outdoor unit. Such bacteria and dust will seriously affect the heat exchange efficiency of the air conditioner, increase the energy consumption of the air conditioner, and reduce the service life of the air conditioner. , so it is necessary to clean the air conditioner in time.

[0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. It is time-consuming and labor-intensive to use manual cleaning. It is ne...
